We're testing out a 5324 and I'm having some problems. For whatever reason, I can't telnet or SSH to the switch, and the web interface intermittently locks up. That's annoying and I'd really like to get SSH to work. Oh, and I can't get in through the console, either. It repeats "Hit any key...Authentication failed. Hit any key...Authentication failed"...

We are using AAA authentication via TACACS+, which is working because I can get in through the web interface (when it's functioning, anyway.) Here's what I see when I try to Telnet or SSH into the switch:

Router#10.1.100.91
Trying 10.1.100.91 ... Open

[Connection to 10.1.100.91 closed by foreign host]
Router#ssh 10.1.100.91
Trying 10.1.100.91...Open

[Connection to 10.1.100.91 aborted: error status 0]

The SSH server is enable, I have "login authentication default" configured on the console, telnet, and SSH lines. The AAA authentication default is configured for TACACS with a fallback to the enable password. The SSH server has been enabled and a crypto key has been generated.

Any thoughts?

Thanks,
John
